dark transverse markings in the cell. An obscure dark band runs from the costa to the 

 end of the cell outwardly and downwardly to near the lower angle of the cell, and then 

 passes perpendicularly downward toward the inner margin, which it does not reach, 

 being lost in the general ground-color of the wing. This dork band is followed out- 

 wardly by a paler bluish band succeeded by a dark shade extending from the costa 

 toward the inner margin. Beyond this there are five or six light points, one on each 

 interspace, these points are succeeded externally by a series of dark quadrate spots 

 on the interspaces. There is a deep, dark brown submaiginal band running evenly 

 from just before the apex to the lower angle of the wing. The fringes are concolorous. 

 The hind wing on the upper side is traversed by three bands of darker color, which are 

 most strongly accentuated on the inner half of the wing and which fade out toward the 

 costal area. The dark submarginal band which is found on the primaries reappears 

 upon the secondaries, being most intense opposite the end of the cell. The wings on 

 the lower side are pale reddish brown, variegated with darker brown spots and bands. 

 The fore wings are paler in color than the hind wings; the basal area is pale chestnut- 

 brown with an oval brown spot near the base of the cell and two transverse, quite 

 broad, dark spots, one near the middle of the cell and the other at its end. All of these 

 spots in the cell are defined outwardly by very narrow pale lines. A very pale light 

 transverse band marks the division between the darker basal area and the 

 lighter outer area of the wing. The series of small light-colored points near the apex 

 of the wing on the upper side reappear on the lower side, where they are much more 

 distinct than on the upper side, and are accentuated externally by deep brown shades. 

 The submarginal band of the upper side appears quite faintly on the lower side, and 

 the outer margin from vein 2 to vein 7 is laved Avith dark chestnut-brown. 



The hind wings on the lower side have the basal area darker than is the case in 

 the fore wing, and are distinctly defined externally by a band of pale lilac. There is a 

 minute dark spot in the middle of the cell, pupiled with lighter color and surrounded 

 by yellowish scales. The outer half of the hind wing is more or less deep chestnut- 

 brown, with a regular evenly curved row of six sharply defined white spots located 

 at the middle of the interspaces from just behind the costa, terminating before vein 2. 

 The submarginal dark band of the secondaries reappears on the lower side in a series 

 of dark lunulate markings parallel to the outer border but not quite reaching the 

 inner border. 



The palpi on the upper side are dark, on the lower side pale brown. The thorax 

 and the abdomen on the lower side are pale brownish white; on the upper side they 

 are dark brown. 



The lower side of the wings recalls in some respects the markings of the under 

 side of the species named umbrina by Aurivillius, but in the outline of the wings, the 

 color and shape of the markings, it is very different, and assuming that the figure of 

 the species given by Aurivillius in Seitz's work is adequate, I cannot reconcile myself 

 at all to refer the insect before me to that species. E.xpanse, 53 mm. 



The type, which is unique, was taken at jNIedje. It is deposited in The Amer- 

 ican Museum of Natural History. 



EuRYPHURA Staudin^er 

 This genus is but poorh' represented in the collection, as is usually 

 the case, for the insects do not appear to be common. It is a difficult 

 genus, both because of the dissimilarity of the sexes and the variabilitv 

 of the females, which are polymorphic in some species.
